Abstract

L'invention fournit un projecteur permettant une projection dans une direction arbitraire. Un premier tube de maintien (41), un premier miroir pliant un premier axe optique (CL1) du premier tube de maintien (41) à 90°, un second tube de maintien (42), un second miroir pliant un second axe optique (CL2) du second tube de maintien (42) à 90°, et un troisième tube de maintien (43), sont disposés sur un axe optique allant d'un côté écran (15) vers un panneau formation d'image (13). Le premier tube de maintien (41) contenant le premier miroir est raccordé au second tube de maintien (42) de manière à autoriser une rotation à intervalles de 90°, au moyen d'une première partie raccordement (44). Le second tube de maintien (42) et le second miroir sont raccordés au troisième tube de maintien (43) de manière à autoriser une rotation à intervalles de 90°, au moyen d'une seconde partie raccordement (45). L'orientation d'une image d'affichage du panneau formation d'image (13) est modifiée, et l'orientation d'une image de projection est adaptée à une image originale sur l'écran (15), selon l'état de rotation d'axe lumineux d'un premier et d'un second capteur.
